The sysfs documentation (Documentation/filesystems/sysfs.rst) recommends using sysfs_emit() instead of sprintf() in sysfs show() callbacks.

Replace the remaining sprintf() calls in the fade_##__dir##_show() macro and color_show() callback with sysfs_emit().

This follows the standard kernel practice and existing use of sysfs_emit() in other Greybus sysfs show functions.

No functional change.

How is this different from past patches that have attempted to change this?

thanks,
